You could easily render a RGB encoded image with 256 colors in your terminal such as in

  use m_rgb_image
  !(...)
  integer :: m, n, i, j
  type(rgb_img) :: img
  m = 254
  n = 254
  call img%init(m,n)
  do j=1, n
    do i=1, m
      img%buff(i, j)%v = achar(int(255*[i*1./m, j*1./n, 0.2]))
    end do
  end do
  call img%render()

which gives the following result
